Company Chairman Sun Hong added that the port would increase capital expenditure next year to 3 billion yuan ($439.6 million), after an asset acquisition from its parent, up from 2 billion yuan this year.
He said the port aimed to boost throughput by 10 percent next year from this year's expected throughput of 46 million TEUs.
With the IPO, the company, already listed in Hong Kong, will become China's first port with such a dual listing.
The new listing would see the company offer up to 1.2 billion shares. Based on the stock's Thursday closing price of HK$3.08 each, it could be worth HK$3.7 billion ($477 million).
Dalian Port has said proceeds from the share offering would be used to invest in its terminal operations and logistics services, to repay bank loans and for working capital. ($1=HK$7.749)
